WILLIAM '1. CLINGER, OF OIL CITY, PENNSYLVANIA.

SUCKER-ROD ELEVATOR.

Specification of Letters Patent.

Patented Aug. 4, 1914.

Application filed February 24, 1914. Serial N 0. 820,703.

To all whom it may concern:

Be it known that I, VVILLIAM T. CLINGER,

drawing sucker-rods from oil wells, such means being usually referred toin the art as sucker-rod elevators.

The object of the device is to provide means of the above describedcharacter which will be simple in form, economical of manufacture andefficient in operation.

The said invention consists of means hereinafter fully described andparticularly set forth in the claims.

The annexed drawlng and the followlng description set forth in detailcertain means embodying my invention, the disclosed means, however,constituting but one of various mechanical forms in which the prin cipleof the invention may be a pplicd.

In said annexed drawing :Figure 1 represents a perspective view of asucker-rod elevator, showing the upper end of a sucker- Fig. 2represents a view similar to that of Fig. 1, showing the parts in adiiferent position. Fig. 3 represents a partial vertical section of theparts shown in Fig. 1 and showing same in the position in which they areshown in the latter figure. Fig. 41 represents a perspective viewshowing the parts in still another position.

The illustrated embodiment of my invention comprises a main-member 1whose upper end is, in the usual manner, provided with a swiveled link 2to which the elevating rope may be attached. Also as in do vices ofsimilar character, the lower end is provided with two arms 3, 3, thelower end of each of which is provided with a bearing 4 for receivingthe trunnions 5 of the slotted plate 6. This plate is similar to thoseheretofore employed excepting that the slot 7 does not intersect theplate angularly as has heretofore been the custom. This said slot 7 isadapted to engage the upper end of the sucker-rod beneath the threadedsleeve 9, as shown in Fig. 1.

Forming an integral part of the mainmember 1 and located intermediatelyof the two arms 3, 3, is a downwardly extending guiding-stem 10 whoselower end lies in a horizontal plane above the end of the suckerrod,when the latter is in position in the plate and said plate occupies ahorizontal position, as shown. Slidable upon said guiding-stem 10 is aSleeve 11 of inverted cu rshape form and having an interior reecss 12adapted to receive the sleeve 9 of the sucker-rod. The upper end of saidsleeve is provided with a groove 18 adapted to receive a key or tongue14 fixedly secured to or integrally formed with the guiding-stem 10, sothat said key or tongue may pass through the upper end of the sleeve, aswill be readily understood.

In the above described construction, it

will be seen that the sleeve 11 may be turned so as to permit the key topass through the slot 13, then raised into the position shown in Fig. 3,and then turned so as to bring the slot 13 out of register with saidkey,

the sleeve being thus permitted to hang in this lifted or raisedposition. When the parts are in the above described position, the mainmember 1 may be turned downwardly as shown in Fig. 1, and in thisposition the plate 6 may be readily caused to engage the upper end ofthe sucker-rod as shown. When it is desired to pull the sucker-rods, theupper end of the latter is caused to engage the slot, as shown in Fig.4, mainmember 1, raised into a vertical position as shown in Fig. 1, thesleeve 1]. turned so as to bring the slot 13 into register with the keyor tongue let, the sleeve then permitted to drop so as to inclose thesleeve 9 of the sucker-rod, and the sleeve then turned so as to bringthe slot 13 out of register with the key or tongue 1 1-. Then the partsare in this position, it will be observed that the upper end of thesucker-rod is prevented from disengaging the plate 6, in which positionthe rods may be pulled, as will be readily understood. It will also beobserved that when the parts are in the above described position, thelower end of the guiding-stem 10 engages the upper end of the sleeve 11,the length of such stem being made sufficient for such purpose, so th tthe main-member 1 is maintained in a vertical position without furthersupport, an advantage which will be recognized by those skilled in theart.

When it is desired to disengage the device from the sucker-rod, theorder of manipulating the various parts as above described, is reversed.

By means of the above described construction, I obtain a sucker-rodelevator which is so arranged that when the rods are being pulled, alldanger of the elevator becoming disengaged from the rods, with theconsequent deleterious results, is eliminated, as will be readilyunderstood by those skilled in the art.

Having fully described my invention, what I claim and desire to secureby Letters Patent is 1. In a sucker-rod elevator, the combination of amain bifurcated member; a member pivotally mounted upon the latter andadapted to detachably engage a sucker-rod; a guiding stem rigidlyconnected with said main member and projecting between saidbifurcations; and a slidable member on said guide-member adapted toengage the end of a sucker-rod while held in said pivotally mountedmember.

2. In a sucker-rod elevator, the combination of a main member; a memberpivotally mounted upon the bifurcations of the latter and adapted todetachably engage a sucker-rod; a guiding-stem rigidly connected withsaid main member; a slidable sleeve mounted upon said guiding-stem andadapted to engage the end of a sucker-rod while held in said pivotallymounted memher; and means for locking said sleeve against slidingmovement upon said stem.

3. In a sucker-rod elevator, the combination of a main-member; a slottedplate pivotally mounted upon the latter; a downwardly extendingguiding-stem rigidly connected with said main-member and terminating ina plane above said plate when the latter is in a horizontal position; asleeve mounted and slidable upon said stem and formed with a recessadapted to engage the end of a sucker-rod; and means for locking saidsleeve in such engaging position.

a. In a sucker-rod elevator, the combina tion of a main-member; aslotted plate pivotally mounted upon the latter; a downwardly extendingguiding-stem rigidly connected with said mainanember and provided with atongue, said stem terminating in a plane above said plate when thelatter is in a horizontal position; a sleeve mounted and slidable onsaid stem and provided with a groove adapted to engage said tongue, saidsleeve having its lower surface intersected by a by a recess adapted toengage the end of a,

sucker-rod; said tongue being of a length such that said groove maydisengage same when in such engaging position.

6. In a sucker-rod elevator, the combination of a main-member; a slottedplate pivotally mounted upon the latter; a down- 'wardly extendingguiding-stem rigidly connected g yith said main-member and provided witha tongue, said stem terminating in a plane above said plate when thelatter is in a horizontal position; a sleeve mounted and slidable onsaid stern and provided with a groove adapted to engage said tongue,said sleeve having its lower surface intersected by a recess adapted toengage the end of a sucker-rod; said tongue being of a length such thatsaid groove may disengage same when in such engaging position; and so asto permit said groove to likewise disengage same when in a raised ordisengaging position.

Signed by me this 18th day of February,
